Back end server modification and visualization

ABSTRACT

Product recommendations are selected according to a model. Product recommendations may be annotated with rules of the model used to select the products. A user may modify the model and be provided with a URL and a cookie associated with the modified model. Subsequent requests or the URL and presenting the cookie are processed using the modified model. A context may be associated with the cookie and modified by the user to observe performance of the model for the context. An interface may permit a user to specify rules for the model or otherwise model its behavior. User interactions with a website result in recommendations according to the model. A journey is recorded that records content, recommendations, and parameters of the model corresponding to the recommendations. The journeys of users may be filtered and visually presented to a user.

RELATED APPLICATIONS

This application is related to U.S. application Ser. No. 15/953,038 filed Apr. 13, 2018, which is incorporated herein by reference for all purposes.

BACKGROUND

In many ecommerce and other web-based solutions, a front end server operates a web server and provides web pages to user devices in response to requests referencing a URL (Uniform Resource Locator). This front end server may submit database queries or other requests to a back end server that implements accesses a database or implements other specific and complex processing functions. The back end server then provides a response to the front end server which may then add the response to a web page that is returned to the user device.

It would be an improvement in the art to facilitate the development and modeling of this type of software architecture.

DETAILED DESCRIPTION

The methods disclosed herein may be implemented in a network environment 100 including some or all of the illustrated components. In particular, a back end server system 102 may execute the methods disclosed herein with respect to browsing activity of one or more user computers 104 a, 104 b. The computers 104 a, 104 b may include desktop or laptop computers, tablet computers, smart phones, wearable computers, interne enabled appliances, or any other type of computing device.

The browsing activities of the computers 104 a, 104 b may include webpage requests submitted by the computers 104 a, 104 b to a web server executing on the server system 102 or be reported to the server system 102 by a third party server or by a software component executing on the computers 104 a, 104 b.

The computers 104 a, 104 b maybe coupled to the server system 102 by means of a network 106 including a local area network (LAN), wide area network (WAN), the Internet, or any other number of wired or wireless network connections. The network 106 may be understood to possibly include one or more intermediate servers by way of which browsing activities of the computers 104 a, 104 b are transmitted to the server system 102.

The computers 104 a, 104 b may execute a browser 108 programmed to retrieve and process data 110, such as by rendering web pages, execute scripts within web pages, formatting website data according to style sheets (e.g., .css files). The browser 108 may execute scripts or process web forms that cause the browser 108 to transmit data submitted through web pages to a source of a web page or some other server system, such as the server system 102.

Communications from the browser 108 may include one or more items of information 112 about the browser itself, such as a type (SAFARI, EXPLORER, FIREFOX, CHROME, etc.) as well as a version of the browser. The browser information 112 may include information about the device 104 a, 104 b on which it is executing such as operating system (WINDOWS, MACOS, IOS, LINUX, etc.), operating system version, processor type, screen size, peripheral devices (e.g., additional screens, audio device, camera), etc. Browser information may include a current time, time zone, font information, storage accessibility (size of local storage 116 described below), location information (e.g., longitude and latitude, city, address, etc.), accessibility information, and the like. This information is used according to the methods disclosed below and may be included in browser requests. Other information (e.g., fonts) may be obtained using executable code executing on one or both of the server system 102 or embedded in website data 110.

The browser 108 may execute one or more browser plugins 114 that extend or enhance the functionality of the browser, such as ADOBE ACROBAT READER, ADOBE FLASH PLAYER, JAVA VIRTUAL MACHINE, MICROSOFT SILVERLIGHT, and the like. In some embodiments, the browser information 112 and listing of plugins 114 may be transmitted with requests for web pages or be accessible by scripts executed by the browser, which may then transmit this information to the server system 102 directly or by way of another server system.

The computer 104 a, 104 b may further include local storage 116 that includes browser-related data such as cookies 118 that are stored by websites visited using the computer 104 a, 104 b.

The server system 102 may access a database 120 storing user profiles 122 a. The user profiles contain data describing a particular user. For example, a user profile 122 a may contain data describing browsing activity, search activity, purchasing activity, and other tracked behavior of a particular user. The user profile 122 a may further include data describing demographic attributes (age, gender, income, profession, geographic location, etc.) as well as other attributes such as interests, hobbies, color preferences, etc. The user profile 122 a may include data from requests received from the user that can be used to characterize the browser 108 or computing device 104 a, 104 b or other context of a request (e.g., time zone, language). In particular, the user profile 122 a may have include any of the data included in a UID (user identifier) record BUID (browser user identifier) record as described in U.S. application Ser. No. 15/788,466 filed Oct. 19, 2017, and entitled BROWSER FINGERPRINTING, which is hereby incorporated herein in its entirety. The server system 102 may likewise implement the methods of U.S. application Ser. No. 15/788,466 in order to populate the user profiles 122 a.

The database 120 may further include a product database 122 b containing records describing products that may be returned as search results or as recommended products while browsing a webpage. The methods disclosed herein are described in the context of providing product recommendations. However, any record may be contained in the database 122 b and selected as a result for display to a user in response to a search term or navigating to a particular web page.

The databases 120 may also store a selection model 122 c. The selection model 122 c may take as inputs a user profile 122 a, context parameters of a browser request (e.g., search terms; data describing a browser; data describing a source device 104 a, 104 b of the browser request; and other context information obtained from the browser request such as location, time zone, language, or the like). The selection model 122 c may process these inputs with respect to the product database 122 b in order to generate a selection of products to provide in response to the browser request. The selection model 122 c may include one or both of a set of rules applied to the inputs and an artificial intelligence model trained to generate a selection of products based on a given set of inputs. For example, the selection model The AI model 116 may be a machine learning model such as a neural network, deep neural network (DNN), Bayesian machine learning model, or the like.

The server system 102 may be a back end server system that operates in cooperation with a front end server system 124. The front end server system 130 may operate as a web server that returns webpages from a website 126 in response to browser requests. The front end server system 124 may further generate requests for product selections to the back end server system 102 in response to such requests. The front end server system 124 may then incorporate these product selections (e.g. images of products, links to products, etc.) into webpages returned to user devices 104 a, 104 b. In other instances, code embedded in webpages provided by the front end server 124 (e.g., JavaScript code) executes on the user devices 104 a, 104 b and requests and receives the product selections from the server system 102 directly or by way of the front end server 124.

The server system 102 may implement a back end module 128 that cooperates with the front end server system 124 and/or code executing on the user devices 104 a, 104 b to receive context parameters of a browser request and provide a selection of products in response according to the selection model 122 c. The context parameters for a request may be any data included in a browser request or in the profile 122 a of a user that can be associated with the browser request. Accordingly, context parameters may include any of the values used to populate a UID record or BUD record according to U.S. application Ser. No. 15/788,466.

The back end module 128 may further execute a preview module 132 enabling a user to modify the selection model 122 c, preview changes, and implement further changes prior to deployment. The preview module 132 may implement the methods described hereinbelow.

Referring to FIG. 2, the server system 102 may implement the illustrated method 200. The method 200 may include receiving 202 a browser request and selecting 204 products according to the context parameters of the browser request. The method 200 may further include annotating the selection of products with rules used of the selection model 122 c that resulted in the selection of the products. For example, a rule may specify a list of co-occurring values for multiple context parameters, a list of values for one or more context parameters that are absent, or any other logic that is applied to the context parameters. The rule may further specify that where the list of co-occurring values or non-co-occurring values, and other logic are satisfied that a particular product or product selection logic should be executed to select a product. Accordingly, where a product is selected according to this rule, a reference to that product in the selection may be annotated to refer to this rule.

The product selection as annotated according to step 206 may then be transmitted to a user device 104 a, 04 b that generated the browser request, such as by way of the front end server 126. The user device 104 a may then render the product selection, such as by displaying images of the selected products, a textual listing of each product in the selection, or the like. The user may then select a rendering for a particular product in the selection. In response to this selection, code executing on the user device 104 a may display a rendering of the rule that annotates that particular product. This enables a user to assess and visualize the functioning of the selection model 122 c.

Referring to FIG. 3, the illustrated method 300 may be executed by the server system 102 in order to test and visualize modifications to the selection model 122 c. The method 300 may include receiving a request to modify the selection model 122 c from a user device (device 104 a for illustration purposes).

In response, the server system 102 may then create a test model that is a copy of the selection model 122 c. The server system 102 may further generate and transmit 308 to the user device 104 a a URL (uniform resource locator) that references the test model. The server system 102 may also generate and transmit 308 a cookie to the user device 104 a. The server system 102 may associate the cookie with a set of context parameters. For example, a user may wish to test the response of the test model to a particular set of context parameters and communicate these set of context parameters to the server system 102. The server system 102 may therefore create a cookie storing this set of context parameters or map the cookie to this set of context parameters. The cookie may then be transmitted 308 to the user device. In some instances, the server system 102 may automatically create the set of context parameters, such as using a pre-defined set of context parameters.

The user may then access the URL, such as by submitting a browser request including the URL and the cookie (or an identifier of the cookie) from the user device 104 a or a different user device. The front end server 126 may receive the request and forward a request for product selection including the cookie to the back end server system 102.

In response to determining 310 that the URL from step 308 was accessed and determining 312 that the request includes the cookie from step 308, the server system 102 generates a product selection according to the set of context parameters of the cookie using the test model and

In response to determining 310 that the URL was accessed and determining 312 that the request included 312 the cookie, the server system 102 generates 314 a product selection using the set of context parameters and the test model according to the approach described above and returns 316 the product selection to the user device that generated the request, such as by way of the front end server 126. This may include generated an annotated product selection using the method 200 of FIG. 2.

Note that the set of context parameters of the cookie are used which may be different from the parameters describing the browser, user device 104 a, or user that generated the request evaluated at steps 310 and 312.

In instances where the URL is accessed but is not accompanied by the cookie, the method 300 may include ignoring the request or processing 318 the request using the selection model 122 c rather than the test model.

Referring to FIG. 4, the illustrated method 400 may be executed by the server system 400 in response to inputs from a user on a user device 104 a, 104 b. In particular, the method 400 provides an approach for modifying the test model thereby enabling a merchant to customize the generation of product recommendations. The method 400 may be used in conjunction with the presentation of a product recommendations using a test model and a set of context parameters as described above with respect to the method 300 of FIG. 3.

The method 400 may include evaluating 402 whether an instruction has been received to change the set of context parameters used to generate product recommendations according to the test model. For example, an interface in a website or client application may be provided by one of the server systems 102, 126 to the user device 104 a. This interface may provide controls enabling the user to instruct the server system 102 to change the set of context parameters, such as in the form of fillable fields, dropdown lists, selectable buttons, uploading a file, or other input approach.

Accordingly, where the user specifies a change to the context parameters, the server system 102 may then process 404 the modified set context parameters using the test model to generate a product selection, which is then transmitted to the user device 104 a, such as according to the approaches described above. In some embodiments, the interface on the user device 104 a may modify the cookie from step 308 that stores the set of context parameters. Code executing on the user device 104 a may then transmit the cookie to the back end server 102, such as by way of the front end server 126. The back end server 126 may then generate a selection of products according to the modified set of context parameters and the test model and transmits the selection to the user device 104 a in the same manner as described in the other examples above. Any of the context parameters described may be modified at step 402, such as those that define the browser request or that could be included in the profile data 122 a of a visitor. As described below, behavior of the test model may be varied over time and certain behaviors may be scheduled for certain periods. Accordingly, modifying 402 the context may include modifying the date of access to a user defined date that is different from the current data in order to view the behavior of the test model on that user defined date.

The method 400 may include evaluating 406 whether the user has provided an instruction through the interface on the user device 104 a to pin a product from a selection to one or more parameters of the current set of context parameters or some other context parameter. In particular, the user may instruct that a particular product or category of products be pinned to one or more value for a context parameter or a set of values for a combination of multiple context parameters. This instruction may be time limited, i.e. specify a date range in which the pinning will be performed. The server system 102 may execute the instruction to pin a product or category to values for one or more context parameters by modifying the test model such that the test model will include that product or a product belonging to that category in the selection of products generated for a browser request including the specified values for one or more context parameters in its set of context parameters.

The method 400 may include evaluating 410 whether an instruction was received from the interface on the user device 104 a to implement a global pin. The global pin instruction may specify that a product or product belonging to a particular category be returned each time a product selection is generated regardless of context. The instruction may specify a time period during which this pinning is to be performed. In this manner a user may promote a particular product for a specified time period. In response to the instruction, the server system 102 modifies 412 the test model to include the global pin such that subsequent product selections will have the product or category of product specified by the instruction during a specified time period or until otherwise instructed when no time period is specified.

The method 400 may include evaluating 412 whether an instruction was received from the interface on the user device 104 a to add a product or category of products to a whitelist. In response to such an instruction, the server system 102 a may add 416 the product or category of products specified in the instruction to a whitelist associated with the test model. Products specified in the whitelist may be selected each time a product selection is generated or may be promoted within internal logic of the test model such that they are selected more frequently than non-whitelisted products.

The method 400 may include evaluating 418 whether an instruction was received from the interface on the user device 104 a to add a product or category of products to a blacklist. In response to such an instruction, the server system 102 a may add 420 the product or category of products specified in the instruction to a blacklist associated with the test model. Products specified in the blacklist will not be included in subsequent product selections according to the test model.

The method 400 may include evaluating 422 whether an instruction was received to add a new rule to the test model. In response to such an instruction, the server system 102 a may add 424 the new rule to the test model. When the test model is thereafter used to generate product selections the new rule will be considered and one or more products may be selected for a product selection when the new rule applies. The new rule may be simple or complex and may take as inputs any number of context parameters of a browser request as specified herein. When a condition of a rule is met, a selection of a product may be made that is likewise a function of any number of context parameters of a browser request. As for other instructions, the new rule may be time limited such that it is only included in the test model for a specified time period before and after which the new rule will not be considered.

Adding of new rules may be performed according to some or all of the following functionality:

-   -   Global Rules: These are rules that enable a merchandiser to         orchestrate the visitor experience for seasonality changes,         product arrivals, short term sales events throughout a site. The         merchant may specify a single global merchandising rule to have         all product recommendations change according to a time specified         by the rule and to include content specified by the rule.     -   Split Testing: A merchant may specify an AB test wherein first         customers are provided a first set of recommendations or         recommendations selected according to a first set of rules and         second customers are provided a second set of recommendations or         recommendations selected according to a second set of rules. The         first and second customers may be selected randomly or the rule         may specify selection of customers for each group according to         attributes or parameters from the user history data 122 a of the         customers.     -   Scheduling: A rule may specify a start date and an end date         between which a specific set of products is to be presented to         customers or during which a specific set of rules are to be used         to select product recommendations for customers.     -   Visual Rules Editor: Rules may be specified using a visual rules         editor that presents products and categories of products. The         visual rules editor may further provide a graphical user         interface to select a product or category of products and to         specify a rule to apply to the selected product. For example,         rules may be applied to first-time visitors to a site in order         to tune the initial experience of these visitors.     -   Dynamic Pages: Dynamic pages enable merchandisers and marketers         to automate the building, updating, merchandising and         personalizing of their Category Pages from their catalog, or a         promotional landing pages (“Virtual Categories”). In particular,         a product catalog may be ingested and category pages generated         for products belonging to a particular category.

As is apparent the method 400 provides means for a user to readily control the test model and customize the generation of product selections for particular products, categories of products, and based on values for any number of context parameters for a browser request.

Steps 402-422 may be performed any number of times to use and modify the test model. When a user is satisfied with the state of the test model, the user may instruct the server system 102 to replace the selection model 122 c with the test model. The new selection model 122 c may then be used to generate product selections according to the methods disclosed herein.

The methods described herein enable a merchant to create merchandising rules and use them across multiple customer touchpoints (website, search results, shopping, email marketing, etc.). This not only reduces the workload of having to create the same rule multiple times but also ensures your rules are completely synchronized when they need to be.

Using the merchandising controls of FIG. 4, a user can orchestrate the customer experience down to the level of a particular product or any category of products at any level of specificity. A user can pin, promote, bury, blacklist, or whitelist a specific product in the interface. For example, a user may drag-and-drop an image of a product into a query based rules editor and provide an instruction with respect to the product according to any of steps 406-422. New rules may be specified based on product categories, sub-categories, attributes of products, and a target contextual audiences based on device, geography, or a buying behavior model. All rules can be scheduled, as well, with start and end dates for promotional and campaign planning.

FIG. 5 illustrates a hierarchy 500 of data structures that may be used to modify the selection model, such as the test selection model. The hierarchy 500 may be used to define modifications according to any of steps 402-422.

In particular, a user may define pages 502 and widgets 504. A page 502 may be a webpage, such as a webpage for a specific product, a specific category of products, a home page of a merchant, or any other webpage providing other information to visitors. A page may be encoded to provide product recommendations and may be generic to multiple products or categories, i.e. a page 502 may be populated with content for a particular product or category of products in response to user request for information about that product or category of products. The product or category of products used to populate the page 502 becomes part of the page's site context as described below.

A widget 504 is a container or data structure that may be embedded in another webpage. The widget 504 could be embodied as executable code, e.g. applet, JavaScript code, or other executable code that can be embedded in code defining a webpage such that a browser will retrieve and execute the widget when the webpage is retrieved by the browser. A widget may also be embedded in an email, search results, or any other document that is rendered on a user device 104 a, 104 b.

In some embodiments, pages 502 are defined by embedding widgets 504 in them such that widgets 504 are the only structure that are used according to the methods disclosed herein. In the following description, the role of widgets 504 to implement recommendations according to the selection model is described. It shall be understood that a page 502 would function in an identical manner.

A widget 504 may include data defining a variation 506. A variation is a set of behaviors 508 that a user wishes to associated with a particular widget 504. Each behavior 508 defines one or both of a user context 510 and a site context 512 to which the behavior 506 applies. The behavior 506 further includes one or more rules 514 that are used to select product recommendations for display by the widget 504 when all of the specified contexts 510, 512 are present. A user may define any number of behaviors 508 in order to customize the visitor experience for many different combinations of user contexts 510 and site contexts 512.

For example, the user context 510 may include a set of attributes of a visitor as determined from forms filled by the user, a user profile data 122 a of the visitor, or any other source of data describing a visitor. Any value for any parameter in the user profile data 122 a may be used to define the user context. For example, the user context may be: “males between 18 and 24 that live in the Los Angeles metro area” or “females between 25 and 35 with children that live on the east coast.” Other examples of user context 510 values may include a type of device used by a visitor to access the webpage including the widget 504, the referring URL, whether the user is a new or returning visitor, the visitor's country, state, region, zip code, or other descriptor of the visitor's geographic location.

The site context 512 may include a keyword, image identifier, product identifier, product category, referring webpage, search string, query string from a referring page, or other data or metadata included in or referenced by the code (e.g., HTML code) defining a webpage in which the widget 504 is embedded. In this manner, a single widget 504 may be embedded in multiple webpages and change its behavior based on the webpage in which it is embedded. Where a page 502 is used, the content used to populate that page is used to determine if the content matches the site context 512 of a behavior 508.

The rule 514 may be any of the rules described above with respect to FIG. 4. For example, a pin-to-context instruction 406 may result in a behavior 508 that includes that context as the user context 510 and the rule 514 may specify that the product pinned should be provided in the recommendations where that user context 510 is present. In a like manner, the rule 514 of a behavior may specify the global pinning (step 410), whitelisting (step 414), blacklisting (step 418), or other rule (step 422) of a product or category of products regardless of context or for a particular user context 510 and/or site context 512.

A rule 514 may specify the boosting or burying of a particular product or category of products. Boosting or burying of a product means that the likelihood of presentation of that product or a product belonging to that category is reduced. For example, where the selection model provides a confidence value for a product recommendation, a buried product would only be presented if the confidence value is at a higher threshold than would otherwise be required if the product had not been buried. A boosted product would be presented when the confidence value is above a lower threshold but below a threshold confidence that would otherwise be required if the product had not been boosted.

In some embodiments, widgets 504 may have inheritance. For example, one or more global behaviors 508 may be defined with corresponding contexts 510 and/or 512 and rules 514. Each widget 504 will therefore include these global behaviors 508 without requiring a user to manually specify them. In this manner, a particular product or policy may be implemented across an entire website and for all merchant advertising without requiring modification of each widget 504. In some embodiments, global behaviors 508 may be overridden by behaviors 508 for a particular widget 504. For example, where a behavior 508 of a widget 504 specifies a rule 514 for a particular set of contexts 510, 512 and a global behavior 508 specifies a different rule for that same set of contexts 510, 512, the behavior 508 of the widget may preempt the global behavior.

In some embodiments, behaviors 508 may be accumulated. In particular, hierarchy may be defined and the widget 504 may be assigned to a node in the hierarchy with one or more ancestor nodes in the hierarchy, each ancestor node having one or more behaviors 508 associated therewith. Accordingly, the widget 504 would accumulate the behaviors 508 of all of its ancestor nodes in the hierarchy in addition to behaviors 508 included expressly in that widget 504.

Note that where A/B testing is desired, a merchant may associate one or more other variations 506 b with a widget 504. Accordingly, either randomly or based on segmentation based on user profile data 122 a, a variation 506 or 506 b may be selected for selecting product recommendations for rendering in a widget 504 in order to implement the A/B test.

Note that pages 502, widgets 504, behaviors 508, user contexts 510, site contexts, and rules 514 may be defined using a graphical user interface (GUI) with drag-and-drop functionality. For example, a product may be dragged and dropped onto a graphical representation of a widget 504 in order to define the site context for that widget. Likewise, user context values may be added using text input fields or by dragging and dropping elements from a palette of user context values.

Referring to FIG. 6, in some embodiments, a customer's “journey” may be captured, where the journey is a record of actions taken by the customer, content accessed by the customer, product recommendations provided to the customer, products purchased by the customer.

For example, the illustrated method 600 may be executed by the server system 102, the server system 124, or a combination of the two. The method 600 may include receiving 602 a user action. Some non-limiting examples of user action may include:

-   -   Receiving a webpage request from a referring site (e.g.,         FACEBOOK, GOOGLE, a partner site).     -   Receiving a webpage request from the customer clicking on an         advertisement;     -   Receiving input of a search term in a search field     -   Receiving a customer's selection of a search result     -   The customer scrolling through search results     -   The customer selecting a recommended product     -   The customer adding a product to an electronic shopping cart     -   The customer purchasing a product.

The method 600 may further include generating 604 a result according to the action and the customer's profile. In particular, where a webpage is requested, that webpage may be returned along with a set of product recommendations that are generated based on the profile of the requesting customer (if available) and the identity of the requested webpage. In particular, if the user selects and advertisement for a specific product, the recommended products may be of the same category as the specific product, for use with the specific product, purchased along with the specific product by other users, purchased after viewing the specific product, or having some other relationship to the specific product. The recommended products may further be filtered or selected based on interests and demographics of the customer as recorded in the customer's user profile data 122 a, provided the customer has a profile and the action can be associated with the customer.

The manner in which recommendations are generated for a customer action maybe according to any approach known in the art. For example, product recommendations may be made using a selection model as defined and modified using the approach described above and as discussed in U.S. application Ser. No. 15/788,466.

The method 600 may further include updating 606 the user profile data 122 a of the customer. In particular, the user action may communicate something about the interests of the user, such as the identity of a product in an advertisement selected or for which the webpage was requested. Accordingly, the user profile data 122 a may be updated to indicate an interest in that product. Where the action is entry of search terms requested by the user (e.g., product, product category, colors, activities, genres, or other information communicated by the search terms) these search terms may be used to update the profile of the customer to indicate interest in the concepts represented by the search terms.

The method 600 may further include recording 608 a record corresponding to the user action. The record may include a representation of the user action, i.e. parameters describing the user actions listed above, i.e. the referring webpage, the advertisement clicked, the search terms provided, scrolling action performed, recommendations clicked on, products added to a cart or purchased, or any other data representing the product or webpage interacted with by the customer or information provided by the customer as part of the action.

The record of an action may further include identifiers of recommended products as a result of the action. The record may further include one or more parameters of a model used to select the recommended products. For example, many artificial intelligence models will output a confidence level with an output of the model. The confidence level is an estimate of the accuracy of the output. In this case, the confidence level of a recommended product as a result of the action may be stored in the record. The confidence level may represent a likelihood the customer will select the product and therefore indicates an affinity of the customer to the recommended product according to the model. The confidence level may also be viewed as a probability of selection or a predicted click-through rate for the recommended product. Other parameters of the model may include rules applied to select the product (see discussion of FIG. 2, above).

The records of each action may be stored, such as part of the user profile data 122 a of the customer. Accordingly, the records in order of creation represent the journey of the customer.

Referring to FIG. 7, the journeys of a customer or of a group of customers may be presented to a user. For example, a user may specify filtering 702 according to profile attributes, such as customer's belonging to a specific demographic (e.g., Male, 18-24, living in Los Angeles metro area).

A user may specify filtering 704 according to journey attributes. For example, user's may be filtered based on how a journey started, e.g. those customers who begin interacting with a merchant due to a referral from FACEBOOK, those customers who clicked on the same advertisement content, or other type of referral. Filtering may be based on purchases, e.g., those journeys that included the customer purchasing something, those journeys that included purchase of a specific product or class of products. Filtering may be based on intermediate actions within the journey, e.g., those journeys that included a customer action with respect to a first product (clicking on advertisement for the first product, searching for the first product, selecting a recommendation for the first product) but were followed by customer purchase of a second product different from the first product. Journeys may be filtered based on length, e.g. length of time or number of customer actions, between starting of the journey and purchasing of a product.

Those journeys that satisfy the filter criteria of steps 702 and 704 may then be presented 706 to the user. Where multiple journeys satisfy the filter criteria, the user may be presented with a listing of the journeys, which the user may then select to view details of a specific journey. A specific journey may be displayed in the manner shown in FIG. 8. Listings may also be displayed simultaneously, e.g. side-by-side or as a matrix.

Other operations may be performed with respect to a set of journeys, such as a set of journeys meeting a filter criteria. For example, pattern analysis of the user actions and the data recorded for each user action may be used to determine a most common path to purchasing of a product.

Referring to FIG. 8, a journey may be represented in various stages, each stage corresponding to a particular customer action 802 a-802 d. The stage for a customer action 802 a-802 d may include context data 804 a-804 d provided to the customer in response to the customer action 802 a-802 d, product recommendations 806 a-806 d provided to the customer along with the context data 804 a-804 d, and model parameters 808 a-808 d relating to the selection of the product recommendations 806 a. Journeys may be displayed in real time, e.g. as the user is taking actions, these actions and corresponding context, recommendations, and model parameters may also be displayed. For example, a filter criteria may be all journeys where the user is current performing user actions (e.g., has performed an action within the last N seconds or minutes, where N is a predetermined time window preceding the current time).

The representation of the user action 806 a-806 d for a stage may include a graphical representation of a link, advertisement, or other visual element selected by the user as part of the user action. Where the user action is entry of search terms, these search terms may be displayed as the user action 806 a-806 d. The context data 804 a-804 d may be a webpage, list of search results, or other data provided to the user as a result of the user action, i.e. the data requested by the customer.

The representation of a stage may also include the product recommendations 806 a-806 d selected for the user as a result of the action and the model parameters 808 a used to select the products for the product recommendations. The model parameters 808 a-808 d may include some or all of the model parameters noted above as being stored in the record for a user action (see description of step 608).

The stages of the journey may be displayed simultaneously or may be scrolled through individually or displayed simultaneously. For example, each stage may be represented by an entry in a list presented to the user. In response to selection of or scrolling to an entry, the data for that stage may then be displayed as shown in FIG. 8.

FIG. 8 further illustrates how a journey may be defined. Other than the first customer action 802 a, each subsequent action 802 b-802 d added to a journey may be constrained to be at least one of (a) a result of a user action with respect to the context 804 a-804 c of a preceding customer action 802 a-802 d in the journey, (b) a result of a user action with respect to a product recommendation 806 a-806 c of a preceding customer action 802 a-802 c, (c) purchase of a product added to an electronic shopping cart during at least one of (a) and (b) for another customer action 802 a-802 c in the journey. Accordingly, a new journey may begin with entry into the web site from a referrer or other access of a webpage the web site that is not the result of interaction with another webpage of the website, such as an interaction according to (a), (b), or (c) in some embodiments.
